The Smart2FA app generates secure 2 step verification tokens on your device. It helps you protect your account by adding an additional layer of security. Just enable the two-factor authentication in your account settings for your provider, scan the QR code provided and you're good to go!

Smart2FA support the TOTP algorithm. This algorithm is industry-standard and making Smart2FA compatible with thousands of services. Any web service that supports Google Authenticator will also work with Smart2FA Authenticator.

A time-based one-time password (TOTP) is a temporary passcode generated by an algorithm that uses the current time of day as one of its authentication factors. A time factor restricts user authentication to a specific time window in which logging on is permitted and restricts access to the system outside of that window.
